Definitions

  • the present invention relates to a mechanical device and a method evacuation of foreign bodies from the inlet channel of a coin mechanism. More particularly this system focuses on the portion of the path traveled by coins located between the coin insertion slot in the coin mechanism and the part measurement area. This path is called the input channel.
  • a coin mechanism is a device that validates and accepts coins used means of payment integrated into a sales machine, such as a merchandise or a public telephone.
  • the coin mechanism includes a case fitted orifices of which the first, substantially vertical, is used for the introduction of the parts. This the latter is accessible from the outside of the PLC, through a mouthpiece with a slot. A coin inserted into this slot enters the coin box by traversing a downward inclined channel before reaching the measurement area where it is analyzed according to different parameters such as dimensions and material. Based on the results of this analysis, the part ends up through a second orifice in an intermediate storage locker then in a case (acceptance), otherwise it is diverted to a return receptacle (rejection).
  • the invention is located at the entry of the coins into the coin mechanism. Indeed, the orifices located on the faces accessible to users of an automaton or a public telephone are regularly obstructed by waste such as pieces of paper, and other unwanted items.
  • the dimensions of the mouthpiece intended for receive the parts are adapted to those of the largest and thickest of acceptable parts. The form of this access already prevents the introduction of larger dimensions than standard parts. In many cases devices placed in public places, the entrance to rooms is obstructed by flexible and deformable objects. They block the inlet channel preventing the introduction of coins which makes the device unusable.
  • the object of the present invention is to propose an inexpensive device for removing foreign bodies from the inlet channel of a coin mechanism comprising means for clearing and evacuating foreign bodies.
  • the presence of a such a device avoids breakdowns of an automaton due to the jamming of the coin mechanism by unwanted objects which can only be removed during on-site interventions from a maintenance service.
  • the valve closes the window of the wall of the canal inlet so that the valve surface replaces the wall portion open so that the pieces are guided in the channel without crossing the window.
  • the shutter is held against the window by the force of gravity thanks to the angle compulsory inclination orienting the coin box when mounted in a PLC.
  • the device is completed by a lever, called the ejection lever, consisting of an arm articulated around an axis perpendicular to the planes of the walls of the inlet channel.
  • the lever is mounted so that the path of the arm crosses the inlet channel between the second wall and the valve when the lever is actuated by a button adequate.
  • this arm is folded down by a return spring in an area contiguous to the channel thus freeing the passage of parts.
  • This ejection lever allows push parts or other hard objects blocking the channel towards the entry slit of so that you can easily remove them.
  • the ejection lever alone no longer allows to evacuate them. Objects can be compressed between the lever arm and the walls of the channel, which causes the blocking of the lever which no longer returns in its rest position. This problem of blocking the ejection lever is resolved by the valve which is lifted by the thrust of the lever arm on the foreign body which thus crosses the wall window to exit the coin mechanism.
  • a foreign object introduced into the inlet channel such as a piece of paper through example can also be evacuated directly through the window covered by the flap by means of a coin. Indeed, this one, while rolling in the channel, pushes the foreign body towards the valve which lifts allowing its evacuation.
  • Figure 1 shows the upper part of the coin mechanism which includes the entry slot (1) where the coin (2) is introduced into the inlet channel comprising a window (3) in the left side wall.
  • This window is closed on the largest part of its surface by a valve (4) provided with an axis (5) rotating freely on bearings secured to the coin box. Stops (6, 6 ') are supported on the edges of the window to prevent the valve from entering, when closed, into the inlet channel preventing the passage of the room. After traveling the canal the part enters the measurement zone (8) where it is analyzed. For some reasons of visibility the ejection lever fixed to the axis (7) is not shown on this Fig.
  • Figure 2 is a side view of the inlet channel showing the valve (4) raised and the ejection lever (11) in its rest position, the arm of this lever being located in an area outside the actual entrance channel.
  • the position of the lever (11) is held by a return spring (12) wound in a spiral around the axis of rotation (7).
  • a button located for example on the front panel of the PLC allows to exert a force on the end (13) of the lever which causes its rotation around its axis (7).
  • the lever arm sweeps most of the interior of the inlet channel.
  • a metal part (2), inserted in the entry slot (1), is retained on the left by the valve (4) which is in the closed position and to the right by the second wall of the input channel. It passes in front of a metal detector (not shown) located behind the second wall of the inlet channel, then rests briefly on a barrier (9) in front of the entrance to the measurement area.
  • This barrier (9) activated, following the detection of a metal part, opens by retracting into the wall of the channel to allow the workpiece to pass through the measurement area.
  • a non-metallic part or foreign body remains in the inlet channel because it is not detected and the opening of the barrier (9) is therefore not activated.
  • Such a body foreigner is then extracted from the inlet channel using the ejection lever (11), the arm pushes the foreign body towards the entry slot (1) where it can be grasped.
  • the thickness of the lever arm corresponds to the width of the inlet channel.
  • An area minimum of the order of a tenth of a millimeter for mechanical play separates the faces of the arm of the second wall of the channel and of the valve (4).
  • the ejection lever (11) by its rigidity, its shape and its dimensions allows the evacuation of most of the non-metallic foreign bodies through the inlet slot or the valve (4).
  • a metal object such as a washer or a coin invalid is returned by the return receptacle at the exit of the coin mechanism.
  • such an object is detected at the entrance and then causes the barrier to open (9) to cross the measurement area (10) where its analysis leads to a negative result. The object is then diverted to a channel leading to the rendering receptacle.
  • Figure 3 shows the valve (4) in its closed position or rest position, the stops (6, 6 ') resting on the edges of the window (3).
  • the surface of the valve (4) does not only partially closes window (3), the remaining opening is too small to that a part (2) can pass through it.
  • This space is desirable, on the one hand for eliminate small objects and on the other hand, it facilitates the exit of the bodies foreigners, when the valve (4) is raised. They are thus evacuated by a larger opening.
  • the ejection lever (11) is actuated by force F on its end (13) transmitted by pressing a button, called the eject button, located for example on the front panel of the PLC.
  • the lever arm travels almost the entire inlet channel by touching the valve (4) and the right wall.
  • the return spring (12) returns the lever (11) to its rest position illustrated by the Figure 2, when the eject button is released.
  • the lever arm thus sweeps the internal face of the valve (4) and of the second wall when it is actuated, either by the force F exerted on its end (13), either by the return force of the spring (12).
  • a foreign body having passed through the window (3) after lifting the valve (4) falls, either at the bottom of the case of the automaton, or, according to a variant, in a special pocket.
  • the latter is mounted under the window (3) against the wall outer left of the coin mechanism.
  • Evacuation by a different route than that of parts return receptacle has the advantage of avoiding blockage of the receptacle or from the channel leading to it.
  • a case of fraud consisting in blocking the receptacle to retain the coins returned by the coin mechanism and then recovery using appropriate tools is thus avoided.
  • FIG. 4 illustrates a variant of the valve (4) comprising a protuberance or relief (15) on the upper edge of the internal face constituting the left wall of the channel input.
  • This relief (15) makes it possible to actuate the opening of the valve (4) jointly by the pressure exerted by the arm of the ejection lever (11) on the foreign body and by the thrust of the lever arm on the relief (15).
  • valve (4) can be operated even if there is no foreign body in the channel. Indeed, the valve (4) lifts under the action of the arm of the ejection lever (11) which, in traversing the inlet channel, pushes on the relief (15) lying across its path.
  • This variant allows more efficient "cleaning" of the inlet channel by pressure successive on the eject button located for example on the front face of the PLC.
  • the lever arm lifting the valve (4) during each of its passages in the inlet channel.
  • the axis (5) of the valve (4) includes a return spring ensuring better maintenance of the position of rest of the valve (4).
  • certain coin insertion mouthpieces (2) mounted on the panel the machine opposite the coin insertion slot (1) of the coin mechanism, deflects the parts towards the valve (4).
  • the parts (2) can thus push the valve (4) which is This raises their unwanted exit from the coin mechanism through the window (3).
  • the return force of the spring therefore contributes to improving the guiding of the parts in the inlet channel by keeping the valve (4) in a more stable rest position in order to avoid inadvertent falling of the parts out of the inlet channel.
